Registered electrician in Carrigaline, Co. Cork.
Services
Most of the work on this board is what Irish law calls Restricted Electrical Works: only a registered contractor can do it, and it has to be certified when it's done. Emmet is registered for all of it.
More sockets where you actually need them, a circuit of its own for a home office or garage, or a weatherproof socket out the back for the garden. New circuits are run neatly, tested and added to your board chart.
New lighting circuits and upgrades: LED downlights, pendants over an island, strip lighting under the wall units, outside lights, dimmers and two-way switching on stairs and landings.
An old board with rewireable fuses, no RCD, or a crack or scorch mark on the casing is worth replacing. The new board protects each circuit properly, trips only the circuit with the fault, and comes with a labelled chart and a certificate.
The protection on your board only works if the earthing behind it does. Where it isn't up to standard, Emmet upgrades the earthing arrangement: the earth electrode, the main earthing conductor and the bonding to your water and gas pipes.
Full and partial rewires for older houses, or for the rooms you're renovating anyway. Planned around how you'll live in the house, with sockets and switches where they make sense.
First and second fix for extensions, new kitchens and attic conversions. Emmet works to your builder's programme and leaves you with the circuits, the lighting and the paperwork in order.
A home charger on a circuit of its own, with the protection it needs, mounted where the cable reaches the car without trailing across the drive. Emmet checks your board and supply can take it before anything is fitted.
An RCD that keeps tripping, a run of dead sockets, lights that flicker. Emmet traces the fault to its cause and fixes it, rather than resetting the switch and hoping.
Lighting
Good lighting is wired in zones, each on a switch of its own: bright light to cook by, a pool over the island, a wash along the worktop and a low glow for the evening. Try the switches.
New kitchen, an extension, or tired halogens that want to be LED? Emmet will walk the room with you and wire it the way you'll use it.

It matters because most electrical work in an Irish home is Restricted Electrical Works, and by law only a Registered Electrical Contractor can carry it out and certify it.
In a home it covers most things: installing or replacing circuits, changing or modifying the fuse board, work in bathrooms and shower rooms, new installations that need connecting to the network, and inspecting and reporting on an existing installation.
Changing a light fitting or a socket faceplate like for like is usually minor work, but it still wants someone who knows what they're doing.
Yes, whenever the job needs one. A registered contractor has to issue a Completion Certificate for electrical work other than minor works, and the original copy is yours to keep.
Not always. The signs are rewireable fuses (the old ceramic kind with fuse wire), no RCD, a casing that's cracked, scorched or warm, or a board so full there's nowhere to add a circuit.
Emmet will tell you honestly whether yours needs to go, and he checks the earthing at the same time, because a new board relies on it.
Your earthing gives fault current a safe path so the protective devices on the board can switch off in time. In older houses the earth electrode, the earthing conductor or the bonding to the water and gas pipes is often missing, undersized or corroded.
Upgrading it means bringing those parts up to the current wiring rules, and it's often done alongside a fuse board change.
